ABSTRACT

The present invention relates to a liquid crystal display panel packing box, including a box body formed with a bottom plate and four side plates that join together. The inner side of each of the side plates is provided with a strip concave-convex channel structure, and the inner side of the bottom plate is provided with a grid concave-convex structure corresponding to the strip concave-convex channel structure.

BACKGROUND

The present invention relates to a liquid crystal display (LCD) panel packing box, and more particularly, to a packing box that is able to carry LCD panels of various sizes.

With continuous development of the liquid crystal manufacturing techniques, there have been LCD panels of various sizes. Due to various sizes of LCD panels, packing boxes having corresponding various sizes are required to carry the LCD panels so as to prevent the LCD panels from being damaged in transportation. However, it is expensive to produce a mold, so the manufacturing cost for making packing boxes for LCD panels of different sizes is high. There are two kinds of packing boxes currently used for loading LCD panels of 17-inch and 20.1-inch, respectively. The packing box for 17-inch is typically used only for loading the 17-inch LCD panel, while the other types of LCD panels, such as 15-inch, 15.4-inch, 19-inch, 19-inch wide screen, 20.1-inch LCD panels, are typically carried by the packing box for 20.1-inch, which imposes a limitation on practice. The box used currently for loading LCD panels only has grooves on two opposite sides, that is to say, the LCD panels can be arranged only in one direction. Moreover, the length of the internal space in a packing box is fixed, so when a LCD panel of an unmatched size is carried by the packing box, the LCD panel is subject to abrasion, shock, impact during loading and transporting and easy to be damaged.

SUMMARY

A liquid crystal display (LCD) panel packing box is provided according to an embodiment of the invention, including a box body formed with a bottom plate and four side plates that join together, wherein the inner side of each of the side plates is provided with a strip concave-convex channel structure, and the inner side of the bottom plate is provided with a grid concave-convex structure corresponding to the strip concave-convex channel structure.

The LCD panel packing box according to an embodiment of the invention can be used to carry LCD panels in different direction and moreover adapt to loading LCD panels of various sizes with the aid of the backing block. Furthermore, loading LCD panels by the packing box may prevent the LCD panels from being subject to abrasion, shock, impact and thus may ensure the panels not be damaged in loading and transporting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1

The embodiment of the invention provides a liquid crystal display (LCD) panel packing box, including a box body formed with a bottom plate and four side plates that join together, the inner side of each of the side plates is formed with a strip concave-convex channel structure, and the inner side of the bottom plate is formed with a grid concave-convex channel structure corresponding to the strip concave-convex channel structure.

A rectangular packing box is taken as an example in the embodiment, as shown in FIG. 1. The inner sides of the four side plates of the box body 1 are formed with a strip concave-convex channel structure 4, and the strip concave-convex channel structure 4 on the opposite sides are disposed at the same positions. That is to say, if a groove is formed on the inner side of one side plate, then a corresponding groove is formed at the same position on the inner side of the opposite side plate so as to ensure the LCD panel to be loaded into the packing box with the grooves on the opposing side plates. The number of the grooves can be determined according to the size of the packing box and the number of LCD panels to be loaded therein.

The inner side of the bottom plate of the box body 1 is provided with a grid concave-convex channel structure 2 corresponding to the strip concave-convex channel structure 4 on the side plates of the box body 1, as specifically shown in FIG. 2, and the grid concave-convex channel structure 2 is in a grid structure formed by the grooves perpendicularly intersecting each other. As shown in FIG. 3, the grooves in the grid concave-convex channel structure 2 correspond to the grooves on the side plates of the packing box. The grooves of the grid concave-convex channel structure 2 ensure LCD panels to be loaded in the packing box smoothly, and three of the four sides of a LCD panel can be disposed and secured in three grooves on the inner sides of the side plates and the bottom plate of the packing box, respectively. With such a structure, the LCD panel can be always held in a space enclosed by the grooves and thus be prevented from being subject to abrasion, shock, impact as well as from being damaged. In addition, a cover may be provided for sealing the packing box, so that the LCD panels can be transported more reliably in a clean circumstance.

Embodiment 2

The inner sides of the four side plates of the packing box according to embodiment 1 is provided with groove structures, so LCD panels of different sizes can be loaded by a lateral packing or a vertical packing selectively according to the LCD panels' sizes. Further, a backing block 3 can be disposed in the packing box to meet the requirement that LCD panels of various sizes can be carried by only one packing box. The inner side of at least one of the four side plates is provided with a backing block 3, both sides of which is provided with a strip concave-convex channel structure also. The concave-convex channel structure on one side of the backing block 3 matches the strip concave-convex channel structure of the side plates 4, while the concave-convex channel structure on the other side of the backing block 3 is the same as the strip concave-convex channel structure on the side plates 4. As shown in FIG. 4, one side of the backing block 3, i.e., the side A, is provided with several convex portions 5, and the opposite side to side A, i.e., the side B, is provided with several grooves 6 corresponding to the convex portions 5. As shown in FIG. 5, the convex portions 5 of the backing block 3 match the strip concave-convex channel structure on the inner side of the side plates of the box body 1. The grooves 6 on backing block 3 replace the grooves on the inner sides of the side plates of box body 1 at the same position. To prevent the LCD panels from being subject to abrasion during loading, for example the packing box can be made of foamed polypropylene, which is a high crystalline polymer/gas composite material and friendly to environment. Also, such material is an anti-pressure backing material with a heat-insulation characteristic.

The backing block in the embodiment can reduce the distance between the side plates in the packing box while maintaining the relative position relationship between the grooves on the backing block and the grooves on the grid concave-convex channel structure on the bottom plate of the packing box. The distance between inner sides of the packing box is reduced with the backing block, and thus the packing box with the backing block will be more convenient to carry LCD panels of various sizes.

Embodiment 3

A packing box of a specific size for LCD panels is provided as an example according to the embodiment of the invention. As shown in FIG. 6, in the packing box according to the embodiment, the strip concave-convex channel structure on two opposite side plates and the grid concave-convex channel structure on the bottom plate enclose a cuboid space having a length “a” of 427 mm, a width “b” of 220 mm, and a height “c” of 10 mm, respectively. The strip concave-convex channel structure on the other two opposite side plates and the grid concave-convex channel structure on the bottom plate enclose a cuboid space having a length, width, and height of 325 mm, 220 mm, and 10 mm, respectively. The grooves in the strip concave-convex channel structure and the grid concave-convex channel structure is configured with a certain depth to ensure the LCD panels being fixed therein, and the depth may be about 10 mm˜20 mm; in this example, the depth of the grooves is selected as about 10 mm, and the width is about 10 mm. As shown in FIG. 7, when the packing box is used for loading a 19-inch wide screen LCD panel having a length and width of 419.6 mm and 265.7 mm, respectively, since the length of the 19-inch wide screen LCD panel approximates that of the packing box, the panel may be loaded in the length direction of the packing box, that is, in the direction L. As shown in FIG. 8, when the packing box is used for loading a 20.1-inch LCD panel having a length and width of 421.8 mm and 319.8 mm, respectively, the panels may be loaded in the width direction of the packing box, that is, in direction W, so that the width direction of the LCD panel when the panel is loaded corresponds to that of the packing box. In addition, the panels may be loaded in the length direction of the packing box, that is, in the direction L, so that the length direction of the panel corresponds to that of the packing box.

When the packing box is used for loading small-sized LCD panels, a backing block may be inserted into the packing box to reduce the size of the internal space of the packing box. As the convex portions on one side of the backing block engages the grooves on the inner side of the side plates of the packing box and the other side of the backing block is provided with grooves at the same position as that on the inner side of the side plates of packing box, the loading method need not to be changed. Two backing blocks can be added along the width direction of the box body, the strip concave-convex channel structure on the backing block and the grid concave-convex channel structure enclose a cuboid space having a length, width, and height of 322 mm, 220 mm, and 10 mm, respectively. For further description, loading a 15-inch LCD panel having a length and width of 314.5 mm and 239.3 mm respectively is taken as an example, two backing blocks are added along the width direction of the packing box, that is, along the direction W, and after adding the two backing blocks, the packing box has a width of 322 mm in the width direction, which matches a length of 314 mm in the length direction of the LCD panel. Moreover, the box is also suitable for loading a 19-inch or 20.1-inch LCD panel. The height of the backing block is not too low to give rise to a right-and-left movement during transportation, and such movement may cause high frequency contact and impact between the LCD panel and the four side plates; the height also may not be too high to waste raw materials and increase cost. Typically, the height of the backing block is set to be not lower than a half of the height of the packing box and not higher than that of the packing box. The number of the backing blocks added can be decided according to the size of the LCD panels to be loaded, and one or more backing blocks may be provided to meet the various sizes of loading LCD panels. The size of the backing block may be designed and manufactured to match the packing box as necessary.
